Re: Concurrent Input Mechanisms

Jason, I think the example might be an page that require you to enable a special mode to use the keyboard. But that special keyboard mode doesn't support  mouse access.

That is the page conforms through settings but the settings when enabled either stop pointer access or break other parts of the page that were previously conformant.

I think Andrew’s suggested formulations are moving in the right direction so far as clarifying the idea is concerned. Obviously, restricting the available input modalities is not a good idea. On the other hand, I don’t know how Web content can fail to satisfy this, in practical terms, or how serious the accessibility issues are that result if it does. In particular, surely most of the issues lie at the user agent or operating system level.

Subject: Re: Concurrent Input Mechanisms

Kathy,
Another tweak, but when I read this it sounds like it is trying to avoid restricting the modalities available on a platform instead of avoiding restricting use of available modalities.

Web content does not restrict user input modalities available on a platform unless it would jeopardize the security of the content, invalidate an activity, or override a user setting.

How about:
Web content does not restrict use of available input modalities on a platform unless it would jeopardize the security of the content, invalidate an activity, or override a user setting.
Or
Web content does not restrict use of input modalities available on a platform unless it would jeopardize the security of the content, invalidate an activity, or override a user setting.
